JOURNAL-BOX.

Specification of Letters Patent.

Application filed July 21, 1908.

Patented Nov. 58, 1911.

Serial No. 4411,60?.

To all wiz/cm it may concern:

lle it known that l, @nantes lf. ltllnnunr, a citizen of the UnitedStates, and resident of Chicago, county of Cook, and State of lllinois,have invented certain new and useful linynoveinents in Journal lieues,of 'which the ffillowing` a specification.

lilly invention relates to journal boxes and has particular reference tomeans for opeiating,` the closure or lid therefor.

l@ne of the objects of my invention is to provide a closure for ajournal box which shall be positive and effective in its action at alltimes. ln order to secure this, it is necessary to so place the springoperating; means that they can not be affected by heat, resulting froman overheated ournal, or from oxidation. To accomplish this end 1conipletely inc-lose the springI within an aperture in the journal boxlu g, closing the end thereof tightly by means of a spring follower.

rl. further object is to provide a journal box of this type which shallbe of the lll/ll. C. B. standard and which shall permit of theinterchange of lids if necessary. lt frequently happens that a lid isbroken on the road and it is desirable that any lll/l. C. ll. lid can beapplied thereto at once.

Further advantages will appear hereinafter.

My invention will be more readily understood by reference to theaccompanying drawings forming a part of this specification and in which;

Figure 1 is a front elevation partly in section showing` my invention;Fig. 2 is a side elevation also in section on the line 2-2 of Fig. 1;Fig. 3 is a horizontal section on the line 3 3 of Fig. 1; Fig'. 4l is aperspective of a cani nut; and 5 illustrates a modification of theinvention shown in Fig. 1.

Referring1 more particularly to the drawings, la is the journal bon; l,is the journal box closure or lid. Upon the top of the journal box, A. lprovide a boss or lug, i', havingan aperture therein, one portion, 7, ofwhich is contracted to the size of the journal box bolt. The mainportion, 8, is slightly enlarged and squared to accommodate a spiralspring', 8, while the outside portion, 9, is still further enlarpged toaceoinmodate a spring' follower, 10 and the squared portion of the bolt.rlhe bolt, l1, has a head, 11a, and a squared portion, 11b. At theopposite end l provide a squared portion, 11C, for the accommodation ofthe cani nut, l2, which has a squared aperture, 12u. .After the partsare assembled the bolt, 11, is headed over the cam nut as at 11d. Thelid, l, is provided with the upstanding portions, 13%13, one edge, 13,of which is provided with a cam surface for cooperation with the camnut, 12. Upon the interior of the lid, B, l provide flanges, 14, adaptedto fit closely within the journal box opening` and flanges, 15, areprovided for fitting; closely around the outer edge of the ournal boxopening Upon the interior of the journal box, A, l provide a dependinglip, 1G. which is adapted to prevent the escape of oil from around thebox opening.

'lhe parts may be assembled as follows: 'lhe spring, 8, is placed withinthe opening, 8, a spring follower', 10, is placed in the opening, 9, andthe lid is placed over the lug, 6. ylhe follower is then held tightlyagainst the lid. rlhe bolt, 11, is then placed in position and the camnut is secured thereon by heading the outer portion, 11d, of the colt,11. Upon lifting` the lid it will be seen that the bolt will revolve thecam surfaces upon the nut and lid, pressing; the spring still farther.As the lid is lifted, the cani surfaces will cooperate against flatportions and the lid may be maintained in any desired elevated position.

Referring to the modification shown in Fig. 5. it will be seen that thebolt` 17, is of uniform diameter, except at itsI ei;- treme end where itis squared at 17L for the accommodation of the cam nut, 18. The lug uponthe journal box has an opening similar to that shown in Fig. 1, its endportion, 19, being` squared for a short distance for the accommodationof a square spring; follower, 20. This follower, Q0, is adapted to besecured to the bolt, 17, by means of a pin, 21. Upon one end of the lid,B, l pro vide a counter sunk portion. 2Q, the inner face of which isprovided with a eain surface, 23, adapted to coperate with the cani nut,1S. yllhe other end of the lid may also be countersunk as shown at 2.41,if desired. ln the top of the lug, 6, of the journal box, l provide aslot, 25, through which the pin, 21, may be placed in or withdrawnfrointhe follower, 20. This construction is assembled as follows: Thespringe; is placed within the aperture, 19, the follower is next locatedin the squared portion, the lid is forced over vthe lug, 6, thuscompressing the spring to a certain eXtent, the bolt is next placed inposition and the cam nut riveted over its squared portion. Upon thelifting of the lid it will be seen that the cam, 23, will reciprocatethe bolt, 17, against the compression of the spring.

The forms above shown are both adapted to be interchanged by any M. C.B. lid by simply removing the spring, replacing the ring, l0, as shownin Fig. l, or the square follower, 20, shown in Fig. 5, thus leaving thebolt opening through the lug of standard size.

As varicus modifications of my invention will readily suggest themselvesto one skilled in the art, I do not confine my invention to the specificconstructions herein shown and described.

Having thus described my invention, I claim as new and desire to secureby Letters Patent:

l. A journal box provided wit-h a lug having an aperture therethrough, aspring and a spring follower within said aperture, in

combination with a lid having a cam surface upon one portion thereof anda bolt adapted to be reciprocated against the compression of said springby means of a cooperating cam upon one end thereof, substantially asdescribed.

2. A journal box having a lug upon its upper surface, said lug beingprovided with an aperture therethrough of varying diameter, a spring anda spring follower held within said aperture, in combination with a lid,and a bolt passing through said spring, spring follower, lug and lid,said lid and bolt having cooperating cam surfaces adapted to reciprocatesaid bolt against the compression of said spring, substantially asdescribed.

In testimony whereof, I have hereunto set my hand this 17 day of July,1908, in the presence of two subscribing witnesses.
